The Square D® Homeline Equipment Protection Device (EPD) Circuit Breakers are 1- or 2-pole thermal-magnetic circuit breakers with integral equipment ground-fault protection. Designed to protect equipment such as heat trace from damage (Class B per UL943), the ground-fault protection level is 30 milliamperes.
What is a QO breaker?
QO® Circuit Breakers QO® (plug-on) one-, two- and three-pole thermal-magnetic circuit breakers provide overcurrent protection and switching on ac and dc systems. Plug-on QO circuit breakers are for use in QO loadcenters, NQ and NQOD panelboards, OEM mounting bases, and Speed-D® switchboard distribution panels.
What is a GFT breaker?
Ground Fault Circuit Interrupters (GFCI) Detect Electrical Leakage which Could Result in Electrical Shock. When Detected the GFCI Shuts Off the Power Instantly. Three NEMA 5-15R Circuit Breaker Protected Outlets.
What does 20A mean on a breaker?
Meaning, when you see or use a 20A receptacle, it is supposed to be telling you that NO OTHER OUTLETS exist on that particular circuit; there is only the wire home run to the panel and it’s own 20A breaker such as a washing machine circuit. On a 15A circuit, per the NEC, you may NOT use a 20A rated receptacle.
How does an EPD breaker work?
An EPD compares outgoing load currents with returning currents to determine if there is leakage of current to ground. If it detects a ground fault greater than 30 mA, the EPD will trip and display the “red flag” of the Visi-Trip® indicator.
What color is the test button on a GFCI breaker?
A yellow test button means it’s a GFCI (Ground Fault Circuit Interrupter) breaker, and a white button means the breaker is an CAFCI (Combination Arc Fault Circuit Interrupter).
Can I use QO breakers in a homeline panel?
These circuit breakers are used for overload and short-circuit protection of your electrical system. Square D Homeline breakers are compatible with Homeline breaker boxes and CSEDs. Square D QO breakers are compatible with QO breaker boxes and CSEDs. Each ANSI-certified and UL-listed.
Is my house 15 or 20 amp?
Tip: The easiest way to determine whether a circuit is 15 or 20 amps is to look at the corresponding breaker or fuse in the breaker panel. Dedicated circuits are electrical lines that carry an electrical current to one single outlet.
Should I use 15 or 20 amp breakers?
The answer: It’s possible, but not advisable without an electrician evaluating the situation. You should never just upgrade from a 15-amp breaker to a 20-amp one just because the current one is tripping. Otherwise, you may burn your house down via electrical fire.
What is the purple button on a circuit breaker?
If the breaker is made by Square D and has the “D inside a square” logo, then the purple test button indicates that it is a Dual Function (GFCI and CAFCI) breaker.
What is the white button on the circuit breaker?
If the breaker is made by Square D, which is the most popular brand of panels and breakers in the U.S., then the yellow test button indicates that it is a GFCI (Ground Fault Circuit Interrupter) breaker and a white button means the breaker is an CAFCI ( Combination Arc Fault Circuit Interrupter).
